CONCRETE CHIMNEY-TOP.

Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed July 21,1905. Serial No- 270,634.

To all whom it may concern:

Be it known that 1, JOHN BAUMGARTNER, a citizen of the United States, residing at Chattanooga, in the county of Mercer and State of Ohio, have invented certain new and useful Improvements in Concrete Chimney- Oaps, of which the following is a specifica tion, reference being had therein to the accompanying drawings. I

My invention relates to chimney-caps, and more particularly to those made of concrete, cement, or other plastic material, one of the objects being to provide a cap or shield to set on the top of a chimney to afford protection thereto, and also one which will aid in preserving the chimney from decay and at the same time prevent debris from falling into the chimney and birds from erecting nests therein, or from carrying material for nestbuilding or other substances into the chimney, such as frequently occurs in localities where chimney-swallows or sparrows are in abundance.

A further object of my invention is to provide a chimney-cap that shall be simple and effective in construction, economical, and which may be easily made of any plastic material and which may also be ornamental and attractive in form and design and one that can be readily attached to brick or stone chimneys of the ordinary well-known construction.

Other objects and advantages of my invention, as well as the structural features by means of which these objects are attained, will be made clear by an examination of the specification, taken in connection with the accompanying drawings, in which the same reference-numerals indicate corresponding portions throughout, and in which Figure 1 is a side elevation of a chimney and showing my improved cap partly in section and in position on top of the chimney. Fig. 2 is a perspective view of my complete cap and showing the wire protector in place in the cap; and Fig. 3 is a perspective view of the wire protector, which fits and rests in the top of the cap to prevent birds or debris from entering the chimney.

1' designates the body portion of a chimneycap, which is comprised of a hollow block constructed in accordance with my invention and preferably composed of some plastic materialsuch as concrete, cement, and the likewhich is durable and lasting and also of a weight to prevent the displacement thereof 1 l the top of a chimney. The top of the cap is preferably serrated, the umvardly-projecting points 2 of the serrations forming means whereby the screen or shield 3 is held against displacement on the inwardlyprojecting shoulder or ledge 4. The screen or shield 3 is preferably formed of a single strand of wire bent upon itself at intervals to form the U-shaped loops 5 and the two outer ends brought together and welded to form a continuous wire, the spaces between the inner ends of the loops 5 being crossed by the bars or rods 6, having their ends bent to form the loops 7, the object of said bars or rods being to add strength to said screen or shield, which can easily be removed from its position in the top of the cap when it is desired to clean the chimney or to repair the same.

A common fault with brick chimneys is their decay, occasioned largely by the inclemency of the weather or the heat imparted to the chimney by smoke or flames arising therein, causing the bricks to crack and the mortar or plaster to crumble and become inadhesive. his decay invariably commences at the top of the chimney and is also frequently occasioned by high winds, together with the other causes hereinbefore named. By the use of my improved chimney-cap, which is both heavy and durable, the top bricks of the chimney are held firmly and securely in position and against displacement by storms or winds and do not fall away, even though cracked by the heat, so that the life of a chimney is much longer when provided with my improved device.

Having thus described my said invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

A chimney-cap comprising a plastic block adapted to sit on top of a chimney and having a central opening therethrough for the emission of the smoke, said block being provided with interiorly-extending shoulders formed integral therewith, in combination, with a wire shield or screen removably mounted on the shoulders and extending across the opening in the block.

In testimony whereof I hereunto a'l'lix my signature in presence of two witnesses.

JOHN BAUMGARTNER.
